Stereoscopic viewing, made possible by the overlap of Apollo mapping
camera frames, does wonders for some lunar scenes. When viewed monoscopically,
these photos taken at high Sun illumination in Mare Fecunditatis show bright
patterns of craters and narrow mare ridges. Viewed stereoscopically, they
reveal the relative depths of the craters; the sharp relief of the narrow
ridges; an unsuspected broad, high swell between the parallel "ranges"
of narrow ridges; and the even more surprising differences in elevation
between mare surfaces in the left (west) and right parts of the photograph.
The elevations of the mare surfaces probably mimic the variable depth of
the buried floor of the Fecunditatis basin. The center of the basin, presumably
the deepest part, is located near the left of the picture, where the mare
surface is lowest. The large crater Messier G is 14 km in diameter.
